-
摘要: 前期研究表明,新型透水铺装通过在结构层引入毛细柱,不仅可有效提高设施在高地下水位地区应用的水文控制效果从而缓解城市内涝风险,还能够有效缓解城市热岛从而调节城市热环境。为了探讨新型透水铺装对于城市雨水径流污染的控制效果,实验构建了新型透水铺装(IPP)、传统混凝土砖缝隙透水铺装(PICP)和不透水混凝土路面(CP)3种不同的停车场现场设施,基于全年实际降雨条件下监测数据,分析对比了IPP和PICP对于雨水径流水质净化的效果差异,评估了2种设施全年所排放的城市面源污染负荷。实验结果表明:与PICP设施相比,IPP对NO3--N、TN的总污染负荷控制率分别从14.4%、37.3%提高至45.6%、58.8%,对TSS和COD总污染负荷控制率分别从81.9%、84.2%提高至97.5%和96.7%;PICP和IPP 2种设施对于TP的去除效果均较好,其总污染负荷控制率分别为82.5%、86.2%。统计结果显示,新型透水铺装IPP可明显减少NO3--N、TN、TSS、COD污染物的排放,从而有效缓解雨水径流导致的城市面源污染问题。Abstract: Previous studies have shown that the innovative permeable pavement, with capillary columns added into the structural layer, can not only effectively improve the hydrological control effect of facilities applied in high groundwater level areas, thereby alleviating the risk of urban waterlogging, but also effectively alleviate the urban heat island to regulate the urban thermal environment. To investigate the pollution control effect of the innovative permeable pavement on urban stormwater runoff, three kinds of parking lots, innovative permeable pavement (IPP), conventional permeable interlocking concrete pavement (PICP), and impervious concrete pavement (CP) were constructed in the Shanghai urban area. Water quality performances of these three pavements were monitored and analyzed under real rainfall events for the whole year. Results showed that the total pollution load control rates of IPP for NO3--N, TN increased from 14.4% and 37.3% to 45.6% and 58.8%, respectively, compared with those values of PICP; the total pollution load control rates of IPP for TSS and COD increased from 81.9% and 84.2% to 97.5% and 96.7%, respectively; moreover, both PICP and IPP had good removal effect on TP, with total pollution load control rates of 82.5% and 86.2%, respectively, indicating that IPP can significantly reduce the emission of NO3--N, TN, TSS and COD, compared with PICP, so as to effectively alleviate the urban non-point source pollution caused by stormwater runoff.
